The utility model relates to the field of filtering and draining, in particular to a horizontal filtration draining body. The horizontal filtration draining body comprises a draining pipe body and a geotextile layer, and is characterized in that the pipe wall of the draining pipe body comprises an pipe outer wall and a pipe inner wall; radial through holes are correspondingly distributed on the pipe outer wall and the pipe inner wall; and the geotextile layer is arranged between the pipe outer wall and the pipe inner wall of the draining pipe body. The horizontal filtration draining body has the advantage of favorable filtration draining effect; the draining pipe of the horizontal filtration draining body is organically combined with the filtration of geotextile, so that the tearing and the voiding of filtering cloth are avoided, the improvement on the construction progress of a project is facilitated, and the construction quality of the project is ensured.
